I’ve lived in NY and have visited Montreal a bunch of times, including one unfortunate trip in January. The average high in January in NYC is almost 40 degrees, and it’s 25 degrees in Montreal.

There will be huge problems but the apocalyptic idea you seem to have is more of a pop culture notion than a scientific one.
